Caution:
The information used to compile this manual has been sourced from the vehicle
manufacturers information and is believed to be the latest available in May 2004.
Manufacturers' information is liable to change at any time and there may have been
updates or revisions which applied to the content of this manual but were not
available at the time of compilation. Later revisions published by the manufacturers
may contain revisions which would be applied retrospectively to the information
contained in this manual.
The information contained in this manual applies only to standard models and does
not apply to vehicles fitted with equipment other than the standard production
options.
Contents
This manual is a comprehensive single source of information on diagnostic trouble codes for engine
management, transmission and immobilizer systems for cars and light commercials introduced or
revised during the period 1994-2004.
The manual is part of a series from Autodata and has been written and presented in a way to enable any
professional automotive technician, with appropriate skills and competence, to make accurate tests and
diagnoses, on the engine management, transmission and immobilizer systems.
Detailed knowledge of self-diagnosis systems is not required to make full use of this publication. With a
basic understanding of fuel and electrical systems, successful trouble shooting and fault repair should be
possible.
Using this manual, in conjunction with the Autodata CD2, or the Pin Data, Engine Management and
Wiring Diagrams manuals, time and expense can be saved by quickly tracing and rectifying the cause of
obscure and/or intermittent faults.
Where possible, procedures for accessing trouble codes without special diagnostic equipment are given,
but increasingly some form of 'scan tool' is required to successfully read the fault memories of control
modules.
Each chapter covers a range of models sharing the same trouble code table and lists the codes in
numerical or alphabetical order with their fault locations and probable causes.
The probable causes column identifies the various different areas of the system that should be
investigated in addition to the primary component in the fault location column.
If a trouble code has been logged, the fault location can be looked up in the trouble code table. This will
give suggested probable causes, which should be the primary areas for checking. Most of these probable
causes will suggest checking the wiring as well as the primary component in the circuit. The multi-plugs,
wiring continuity, insulation and resistance should all be verified before replacing components.

How to use this manual
Find the model related chapter from vehicle manufacturer, model
name, engine code, year of manufacture and system.
Observe the following relevant test conditions:
All auxiliary equipment, including air conditioning, switched
OFF.
Ensure battery voltage above 11 volts.
Ensure earth wires in good condition.
If vehicle fitted with engine malfunction indicator lamp (MIL):
Check MIL operation - if MIL does not flash or illuminate,
replace bulb or repair circuit.
NOTE: If MIL remains illuminated or flashes, this indicates a
fault, but if it goes out there could still be trouble codes
logged in the ECM. Scan tool may not respond if MIL is
not working.
Engine at normal operating temperature.
Carry out road test.
Ensure overrun cut-off function operates several times.
Operate accelerator pedal several times over complete
travel range.
Allow engine to idle.
If engine does not start: Briefly crank engine and leave
ignition switched ON.
Observe any model specific information.
Find the location of the data link connector (DLC).
Bridge DLC terminals, connect an LED tester or scan tool,
as appropriate and observe any special conditions. If a scan
tool is used, follow the manufacturer's operating instructions.
Follow procedure for accessing trouble codes and note any
codes displayed.
NOTE: The trouble code may not identify the exact cause of any
problem, but serves as a guide to the component or
system to be investigated.

system
Check for further trouble codes.
Follow procedure for erasing trouble codes.
NOTE: If the battery is disconnected to erase trouble codes, data
stored, such as radio security codes and ECM adaptive
memory may be lost.
Road test vehicle and recheck for any logged trouble codes.
If a trouble code is output, but not listed in the appropriate
code table, suspect a control module fault.
NOTE: In the case of signal or component malfunction, the ECM
will substitute a fixed value from its internal limited
operating strategy (LOS) software. This enables the
vehicle to be driven in limp-home mode until the fault can
be rectified. Depending on the component or circuit in
question, it may not be obvious to the driver that the
engine management system is operating in limp-home
mode.

Fault location
Fuel trim
-F I ~5.
Short and long term fuel trim refers to the strategy
Fig. 5
used to reduce exhaust emissions after the basic
computation of injection period, using engine load as
the major parameter.
RICHER
Both front and rear oxygen sensor signals are used
to fine tune the fuellair mixture by increasing or
decreasing the injection period +I-25% above or
below the basic level.
Any fault requiring a correction beyond this level will
result in a trouble code being logged.
When the engine is new and running satisfactorily
a level of fuel trim will be established - represented
by 100°/o.
The fuel trim will oscillate the injection period +I-5%
above and below the mean level [A].
Manufacturing and in-service tolerances of load
sensors (MAP, MAF or VAF) and injectors in
particular and faults such as intake air leaks will
affect the fuellair mixture and cause the fuel trim to
quickly compensate.
An intake air leak for instance would result in the
injection period increasing, for example to 115-125%. This level will also oscillate +I-5% as before [B].
This new short term fuel trim (STFT) level will be stored in the ECM if it is established as a new basic mixture level. It will
then become a long term fuel trim (LTFT) correction and results in the correct mixture level immediately after starting,
even when the H02S has had insufficient time to heat up.
Long term fuel trim (LTFT) values can be erased by disconnecting the ECM power supply for a suitable length of time.
If the memory is not erased after repairs the ECM will eventually learn the new LTFT values, but this will take some time
and probably cause high emissions and some driveability problems.
For example if an intake air leak causes the engine to run lean this will be compensated by a change in the LTFT value,
which will be stored in the ECM memory.
After the leak has been repaired this memorised LTFT value will still be used to compute the injection period, resulting in
excessively rich running, until new LTFT values have been learned.
Probable causes
Wiring
Wiring - refers not only to the wiring harness, but also to any associated component multi-plugs, relay plates, welded,
crimped or soldered joints and bulkhead connectors.
Short to earth - refers to wiring that has a 'leak' to earth somewhere along its length e.g. if the insulation has chaffed
through and the wiring is in contact with the body or engine.
Short to positive - refers to wiring that would normally not be carrying 12 volts, but is shorted to the 12 volt supply e.g. a
sensor wire that would normally be fed with approx. 5 volts from the ECM, shorted to a 12 volt battery positive supply.
Open circuit - refers to wiring that is either disconnected or broken, but is not shorted to either earth or a positive supply.
Poor connection - refers to a loose, intermittent or high resistance connection.
General faults
Despite the sophistication of modern electronic management systems, basic mechanical faults can still cause unsatisfactory
starting, running and driveability.
Before assuming that a problem is an electronic one, it should be established that the engine/transmission/immobilizer is in
good mechanical condition and that the basic fuel and electrical circuits are OK.

Safety precautions
Airbags (Supplementary Restraint System
- SRS)
Many of the models covered by this manual are fitted with
airbags as standard equipment. When working on a vehicle
fitted with such a system, extreme caution must be taken to
avoid accidental firing of the airbag, which could result in
personal injury.
Unauthorised repairs to the system could render it inoperative,
or cause it to inflate accidentally.
NOTE: All related wiring is encased in a yellow outer covering.
NEVER attempt to test the system using a multi-meter.
NEVER tamper with or disconnect the airbag wiring
harness.
NEVER make extra connections to any part of the system
wiring harness or terminals.
ALWAYS ensure that the airbag wiring harness has not
been trapped or damaged in any way when working on
adjacent components or systems.
When the engine is started the AIRBAG warning lamp should
go out after approximately 5-10 seconds, if not this indicates a
fault in the system. The system should be checked and the fault
corrected by a competent technician before any other work is
undertaken.
Electrical
ALWAYS ensure that the battery is properly connected
before attempting to start the engine.
DO NOT attempt to start the engine using a source in
excess of 12 volts, such as a fast charger (16 volts) or by
connecting two batteries in series (24 volts). ALWAYS
disconnect the battery before charging it.
DO NOT disconnect the battery while the engine is running.
DO NOT connect the battery with reverse polarity.
DO NOT disconnect or touch the HT leads when the engine
is being cranked or when it is running.
DO NOT connect or disconnect the electronic control
module (ECM), or any other component of the fuel injection
system while the ignition is switched ON.
DO NOT disconnect ECM multi-plug within 30 seconds of
switching ignition OFF.
DO NOT connect or disconnect multi-meters, voltmeters,
ammeters or ohmmeters with the ignition switched ON.
DO NOT reverse the polarity of the fuel pump.
ALWAYS ensure that all electrical connections are in good
condition and making good contact, PARTICULARLY the
ECM connector.
ALWAYS disconnect the ignition coil, ECM, fuel pump
relaylfuse before carrying out a compression test.
DO NOT flash a wire or circuit to ground to check that
continuity exists.
Modern ignition systems operate at very high voltages and
these high voltages can severely damage transistorised
components such as a wrist-watch if electrical contact is
made. Wearers of heart pacemaker devices, therefore,
should not at any time carry out work involving ignition
systems. In addition to the danger from electric shock,
further hazards can arise through sudden uncontrolled
body movement causing involuntary contact with moving
parts of the engine, i.e. fan blades, pulleys and drive belts.
ALWAYS ensure that any replacement fuel or ignition
system parts are correct for the application in question.
Manv units share common external features, but differ
internally.
Mechanical
ALWAYS disconnect the distributor before carrying out a
fuel pump pressure or delivery check.
AVOID the risk of fire - NEVER work on the fuel injection
system when SMOKING or close to a NAKED FLAME.
AVOID the risk of fire - ALWAYS disconnect the ignition
coil supply and ground the coil HT lead, so that NO
HT spark can be emitted, before checking the fuel injector
valves, or any other component of the fuel injection system
likely to result in the presence of fuel in or around the
engine bay.
ALWAYS keep a fire extinguisher close at hand when
working on the fuel injection system.
ALWAYS ensure that test equipment, leads, tools and
especially items of clothing, are clear of moving parts and
are not liable to fall into the engine bay, due to vibration,
when the engine is running.

Tools & equipment
The method of fault code output varies considerably from manufacturer to manufacturer. The simplest to access are flash
type codes displayed with the malfunction indicator lamp (MIL) on the instrument panel Fig. 1 or an LED display on the
control module Fig. 2 - these do not require any special equipment.
Systems r e q u i r i ~ p e c i atools
l
or equipment may output fault memory data as numerical codes or as plain text
messages.
Many different types of diagnostic equipment are available for reading self-diagnosis fault memories.
These vary from simple LED based testers, for reading flash type codes, to software based scan tools fully compatible
with EOBD requirements and incorporating many additional features, including the facility to be connected to a PC and
printer.
Some flash type codes are very complex, with up to ten flashes per group and four or five groups of digits, so that reading
them accurately with an LED tester is difficult and the possibility of miscounting is quite likely.
Some code readers can only display numerical codes, which means that they are unsuitable for use on certain makes and
models (such as Renault, Rover, Fiat etc.). These require equipment capable of displaying fault descriptions in plain text.
Most scanner tools will enable fault codes to be erased without disconnecting the battery, therefore avoiding the loss of
radio codes and control module learnt values.
Any software based equipment will need to be updated periodically by replacement 'pods' or CDs provided by the
equipment manufacturers.
Additional features accessible with the more sophisticated testers include:
Activation and functional testing of specific actuators and sensors.
a Multi-meter ranges.
Recording and displaying oscilloscope patterns.
n Links to menu based fault diagnosis procedures, with wiring diagrams, technical data and fault finding flow charts.

General recommendations
Electronic control modules such as the engine control module (ECM), transmission control module (TCM) and immobilizer
control module need special care during fault diagnosis. They are easily damaged by excess voltage or reversed polarity.
Whenever possible disconnect them before testing wiring continuity.
Some ECMs have an adaptive memory which may have to re-learn its basic dynamic values (during driving) if the power
supply is interrupted, for instance to erase fault codes.
Electrical wiring can be repaired where practicable but ensure that all repairs are properly insulated, preferably with heat
shrink tubing and protected by a fuse of the correct amperage.
NOTE: Many electronic control modules have fault memories which may be erased if the power supply is interrupted.
Check condition of ALL fuses in the system prior to circuit testing.

Tools & equipment
Test equipment
Multi-meter types
The majority of electrical faults identified in this manual can be successfully diagnosed using an ohmmeter or voltmeter.
Normally these functions will be combined in a multi-meter.
A high impedance (10 K ohmslvolt minimum) multi-meter that includes a 0-20 V voltage scale and a low (0-200) and high
(0-20 K) range ohm scale is recommended for measuring the voltage and resistance of the system components.
Analogue meters (with a needle sweeping across a numerical scale),-due to their continuous readout are useful for certain
applications, such as counting needle deflections to identify fault codes on certain models and the identification of
intermittent faults, but for general workshop use a digital meter is easier to use and is more resistant to rough handling and
less likely to be damaged by incorrect use.
Digital meters (with an LED or LCD display), are available in many different types. In addition to the basic, general purpose
meters with voltage (DCIAC), resistance and amperage scales additional features such as temperature, duty cycle and
engine RPM etc. are often incorporated in dedicated test meters for automobile applications.
Using multi-meters
Voltage checking - --Fig. 3, Fig. 4, Fig. 5 81Fig. 6

Set the meter to VOLTAGE.
If applicable, set the meter to the correct scale e.g.
ACIDC, VImV etc. (most modern meters are selfranging).
Connect the black test lead to the negative terminal
being tested.
Observe the conditions of the test, e.g. ignition ON etc.
Connect the red test lead to the positive terminal being
tested.
Read and record the value displayed.
Measurement of voltage drop through cables and
components can be a useful diagnostic tool, as any
abnormal condition will have an effect on the operation
of the circuit(s) and components involved.
The multi-meter should be set to measure milli-volts
and the circuit should be in its normal operating mode
e.g. all multi-plugs connected and current flowing.
Maximum voltage drop should not exceed the following values:
Control module harness wire - 200 mV
Switch - 300 mV
Earth connection - 100 mV
Sensor connection - 50 mV

High resistance in earth connections can cause unusual
(and apparently illogical) symptoms that are seemingly
unconnected with the components involved.
Earth connections should be thoroughly cleaned and
treated with a proprietary contact cleaner before
assembly.
Connections in the vicinity of the battery are particularly
vulnerable to corrosion.
Earth wires should be checked along their whole length for
chafing, corrosion and mechanical damage. A typical
earth wire may have 20-30 strands and although there will
still be a connection if only a few of these are intact, the
resulting high resistance will cause problems.
Suspect multi-plugs should be 'dismantled' (if possible)
and the terminals thoroughly inspected and cleaned.
Set the meter to RESISTANCE.
If applicable, set the meter to the correct scale (most
modern meters are self-ranging).
Connect the black test lead to the red test lead and check
that the meter displays ZERO R.

CAUTION: Circuit testers incorporating a bulb
should not be used on electronic
circuits as the high current involved
could damage sensitive components.
LED testers can be used safely on electronic
circuits as their low current consumption cannot
damage electronic components.
They are particularly useful where a pulse or
intermittent signal is being checked.
Most LED testers are in the form of a probe
attached to the tester body, with a test lead and
clip for the other terminal. The more
sophisticated testers have different coloured

Breakout box - F I ~14
.
Fia. 14
Whenever possible a breakout box should be used for
circuit testing at the control module multi-plug and
when checking pin data.
A breakout box [ I ] is a means of connecting test
equipment to the control module harness without the
need to probe into the back of the harness multi-plug.
For checking pin data it is connected by an adaptor
lead [2], between the ECM [3]and the car's wiring
harness [4].
For circuit testing the harness multi-plug is
disconnected from the control module and connected
to the breakout box.
The pin connections are laid out in rows in numerical
order and have large connecting sockets, enabling test
v ~ ~ 4 2 7 2
leads to be securely plugged into a circuit, and
avoiding the possibility of connecting to the incorrect

pin, due to miscounting.
The possibility of damaging components or wiring, due
to shorting live pins to ground or to other components,
is also much reduced.
The limiting factor is the range of adaptor leads. Several equipment manufacturers produce breakout boxes, but none are
able to supply a complete range of leads to cover all the models included in this manual.

If a breakout box and suitable adaptor leads are not
available, testing must be carried out at the wire side of
the ECM harness multi-plug Fig. 15.
To access the terminals the protective cover must be
removed from the plug. Many different types of plug
are used for engine management wiring harnesses and
two examples are shown in Fig. 16 and Fig. 17.
Use the appropriate ECM harness multi-plug -wire
side diagram and identify the pin(s) to be tested - refer
to Autodata CD2 or Pin Data manual.
Use only very fine test probes to access the
connections and measure the signal between the pin
and earth Fig. 15 [A], or between two ECM pins

Oscilloscopes
Digital multi-meters are entirely satisfactory for checking circuits in a static condition and for instances where any change
in reading is a gradual one, but for dynamic checking and the diagnosis of intermittent faults, the oscilloscope is a very
powerful workshop tool.
Unlike older analogue oscilloscopes dedicated to HT ignition testing, a modern digital oscilloscope has a variable voltage
scale, enabling low voltages (typically 0-5 V or 0-12 V) to be displayed and also an adjustable time scale, enabling any
wave form to be displayed in the ideal manner.
Most oscilloscopes designed for automotive use can be hand-held and are therefore ideal fcr use in the workshop. They
can also be used inside the car, while the vehicle is driven, to capture dynamic data.
Usually it is possible to store wave forms and associated data in an internal memory and then print out or download the
information onto a PC, enabling the scope patterns to be studied in detail.
The oscilloscope display can show the amplitude, frequency, pulse width, shape and pattern of the signal received, by
effectively drawing a graph of voltage (vertically) and time (horizontally).
It is easy to connect (normally just two leads) and the speed of sampling can be far in excess of even the best of digital
multi-meters.
This fast response time enables diagnosis of intermittent problems and also enables the effect of disturbing parts of the
system to be observed. When necessary, the response time can be slow enough to display signals such as the throttle
position sensor.
Once the cause of a problem has been diagnosed and rectified, the repair can be verified by retesting with the
oscilloscope.
The oscilloscope can also be used to check the overall condition of an engine management system equipped with a
catalytic converter, by monitoring the activity of the oxygen sensor.
The complex electronic engine management systems fitted to catalyst equipped vehicles are designed to maintain the
mixture level between quite close tolerances so that the oxygen sensor is able react to small changes in the exhaust
oxygen level and feed this information back to the ECM in the form of a voltage signal. By watching the oxygen sensor
signal with an oscilloscope any irregularity in the overall system performance can be detected. If the wave form displayed
is satisfactory this is a reliable indication that the whole system is operating correctly.
Currently available oscilloscopes are easy to connect and use, enabling a trace to be displayed on the screen without any
specialist knowledge or experience. The interpretation of this trace can be greatly assisted by reference to the typical
wave forms illustrated in this chapter.
Wave forms
-~ i g 1.
Each oscilloscope wave form has one or more of the
following parameters:
Amplitude - voltage (V)
The signal voltage at a certain moment in time
Frequency - cycles per second (Hz)
The time between points of the signal
Pulse width - duty cycle (%)
The period during which the signal is ON - expressed as
a percentage (%) of the total
Shape - spike, curve, saw-tooth etc.
The overall 'picture' of the signal
Pattern - repeated shapes
The pattern of repetition of the overall shape of the
signal
The oscilloscope will show all these parameters in one
display and by comparing the scope traces from the
vehicle under test with those illustrated, a judgement can
be made about the condition of each circuit and its
components.
The scope trace for a faulty circuit or component will
usually appear very different to that for a satisfactory one,
thus simplifying fault identification.
The five parameters listed above can be categorised as
follows:

Interpreting wave forms

Oscilloscope wave form patterns can vary greatly and are dependent on many factors. Therefore prior to making a
diagnosis or changing components the following points should be considered when the wave form obtained does not
appear to be correct when compared with the 'typical' wave form.
Fig. 22
Fig. 23
Mgital wave t o m
Voltage
Typical wave forms indicate the approximate position of the wave form in relationship to the 'zero grid', but this may vary
Fig. 22 [I], dependent on the system being tested and may be positioned anywhere within the approximate 'zero range'
Fig. 22 [2] & Fig. 23 [I].
T h e m p l i t u ~ v e r a l height
l
of the pattern (the voltage) Fig. 22 [3] & Fig. 23 [2], will depend on the circuit's operating
voltage.
For direct current (DC) circuits this will depend on the voltage being switched, for example, idle speed control device
voltage will be constant and will not vary with engine speed.
For alternating current (AC) circuits this will depend on the speed of the signal generator, for example, an inductive
crankshaft position (CKP) sensor's output voltage will increase with engine speed.
Therefore if the oscilloscope pattern is too high (or the upper part is missing) increase the voltage scale to obtain the view
required. If the pattern is too low decrease the voltage scale.
Some circuits operating solenoid components, for example idle speed control devices, may display voltage spikes Fig. 22
[4], when the circuit is switched off. This voltage is generated by the component and can normally be ignored.
Some circuits that have a square wave type of typical wave form may display the voltage decaying at the end of the
switching period Fig. 22 [5]. This is a characteristic of some systems and can normally be ignored, as it does not by itself
indicate a fault. -
-
Frequency
The overall width of the pattern (the frequency), will depend on the circuit's operating speed.
The typical wave forms illustrated show the wave form viewed with the oscilloscope's time scale set to enable detailed
observation.
In direct current (DC) circuits the time scale will be dependant on the speed at which the circuit is switched Fig. 22 [6], for
example, the frequency of an idle speed control device will vary with engine load.

Oscilloscope testing
In alternating current (AC) circuits the time scale will depend on the speed of the signal generator Fig. 23 [3], for example,
an inductive crankshaft position (CKP) sensor's frequency will increase with engine speed.
If the oscilloscope pattern is too compressed, decrease the time scale to obtain the view required. If the pattern is too
expanded, increase the time scale.
If the pattern is reversed Fig. 23 [4], this indicates that the system being tested has its component connected in the
opposite polarity to the typical wave form shown and can normally be ignored as it does not by itself indicate a fault.
Fig. 24
Component testing
Wave forms for a variety of components can be displayed. A
few of the more common examples are described below.
Most modern oscilloscopes have just two test leads, used
with a variety of interchangeable test probes. The red lead is
the positive and is normally connected to the ECM pin. The
black lead is the negative and is normally connected to a
good earth.
If the leads are inadvertently connected with the wrong
polarity, usually the only consequence is that the wave form
will be displayed upside down.
Injectors
All electronically controlled intermittent injection systems
operate by varying the opening time of the injectors to match
the quantity of fuel supplied with the engine operating

conditions.
AD42127
The duration of the electrical impulses from the control
Injector wave farm
module is measured in m~lliseconds(ms) and typically
ranges from 1 to 14. The oscilloscope on most engine testers
can be used to display the injector pulse, enabling the
duration to be measured.
A typical oscilloscope trace is shown in Fig. 24.
A series of smaller pulses, which hold the injector open after the initial negative pulse and a sharp positive voltage spike
may be displayed as the injector closes.
It is therefore possible to check that the control module is operating correctly by observing the changes in injector opening
times during various engine operating conditions.
Pulse duration during cranking and at idle speed will be higher than at low engine speeds, but will increase as the engine
speed rises, up to a maximum at full throttle.
This effect will be particularly evident if the throttle is 'blipped'.
Injector pulse
Using a thin probe, connect the oscilloscope test probe to the ECM injector terminal and the second test probe to earth.
Crank the engine and check the wave form.
Start engine and observe the wave form at idle speed.
Open the throttle rapidly to increase engine speed to around 3000 rpm.
The measured pulse duration should increase during acceleration and then stabilise at a reading equal to or slightly below
the idle speed value.
Close the throttle rapidly and the trace should become a straight line with no pulse indicating that injection has been cut-off
(for systems fitted with overrun injection cut-off).
When the engine is started from cold the quantity of fuel required is increased and therefore the pulse duration or dwell will
be greater.
During warm-up the injection period should progressively decrease until the engine reaches normal operating
temperature.
Systems without a cold start injector usually give additional injector pulses during the cold start, which may be seen as
long and short pulses on the scope.

Oscilloscope testing
Inductive sensors
- Flg. 25
The general procedure is as follows:
Select sensor pin from pin data list with wave form reference.
Connect oscilloscope probe to ECM pin and second probe to earth.
Start engine and observe test conditions.
Compare scope trace with wave form reference.
Raise the engine speed and watch for the voltage (amplitude) display to increase.
ldle air control (IAC) vaive
ldle air control (IAC) valves come in many different types, each with a different wave form.
In each case the duty cycle (or ON time) of the valve should increase when any additional engine load starts to reduce the
idle speed.
If the duty cycle varies but the idle speed is not maintained under load, this indicates a faulty valve.
If the wave form shows a straight line around the zero mark, or the line is constant at the 5 V or 12 V level, this indicates a
fault in the IAC valve circuit or ECM signal output.
The commonly used 4 pin stepper motor type is described below. Two and three pin IAC valves can be tested in a similar
way, but will of course generate very different wave forms.
The stepper motor responds to an oscillating signal from the ECM, enabling small adjustments to be made to the engine
idle speed, in reaction to variations of operating temperature and load.
This voltage signal can be checked by connecting the oscilloscope test probe to each of the four stepper motor ECM pins
in turn.
Ensure engine is at normal operating temperature.
Start the engine and allow idle speed to stabilise.
Increase the load on the engine by switching on the headlights, air conditioning or by turning the steering (power steering
only).
The idle speed should momentarily drop, but then be stabilised by the action of the IAC valve.
Compare scope trace with wave form reference Fig. 26.

Oxygen sensor (02s)
NOTE: The following voltage figures refer to the almost universally usedzirconium type O2S, without a 0,5 V control reference. A
few recent models are fitted with a Titanium sensor which has an operating range of 0-5 volts and shows a high voltage
signal with a weak mixture and a low voltage signal with a rich mixture.
Connect oscilloscope test probes between oxygen sensor ECM pin and earth.
Ensure engine is at normal operating temperature.
Compare scope trace with wave form reference Fig. 27.
If the trace shows no wave form but instead is a straight line, this usually indicates a weak mixture if the voltage is
approximately 0-0,15, or a rich mixture if the voltage is approximately 0,6-1 - refer to Autodata fuel injectiontengine
management manuals or CD for possible causes of this condition.
If the wave form is satisfactory at idle, open the throttle briefly several times in succession.
The wave form should show the signal voltage 'cycling' between approximately 0-1 Volt.
The increasing voltage corresponds to the engine speed rising and the decreasing voltage corresponds to the engine
speed falling.
Knock sensor (KS)
Connect oscilloscope test probes between knock sensor ECM pin and earth.
Ensure engine is at normal operating temperature.
Briefly snap throttle open.
Wave form should display an AC signal showing a considerable increase in amplitude Fig. 28.
If this signal is not distinctly displayed, tap the cylinder block lightly in the region of thesensor.
If the signal is still not satisfactory this indicates a faulty sensor or associated circuit.
Fig. 27

Oscilloscope testing
Ignition amplifier
Connect oscilloscope test probes between ignition amplifier ECM pin and earth.
Ensure engine is at normal operating temperature.
Start the engine and allow to idle.
The signal should show a digital DC voltage pulse.
Compare scope trace with wave form reference Fig. 29.
If the signal is satisfactory the amplitude, f r e q u e n i d shape of each pulse should be closely matched.
Increase the engine speed and check that the signal frequency increases in proportion to the engine rpm.
Ignition coil
- primary
Connect oscilloscope test probes between ignition coil ECM pin and earth.
Ensure engine is at normal operating temperature.
Start the engine and allow to idle.
Compare scope trace with wave form reference Fig. 30.
Positive voltage spikes should be of even amplitude.
Major differences of amplitude could indicate either a high resistance in the secondary circuit or a faulty spark plug or HT
lead (where applicable).
Electronic control modules
Without specialist equipment and data no testing of control modules is possible, except by self-diagnosis (if applicable) or
substitution.
Several companies operate a repair or exchange service for control modules and some offer a diagnosis service via a
modem link to an appointed agent.
However it is possible to check:
0 The signal inputs.
0 The signal outputs.
The wiring.
NOTE: Refer to Autodata Pin Data manual or CDZ for engine management system signal values.
NOTE: For information regarding control module self-diagnosis refer to model-specific chapter in this manual.

Trouble codes
All the systems covered by this manual are controlled by a module which incorporates a self-diagnosis function. These control
modules are capable of detecting certain faulty signals and storing them for access later.
In many cases the detection of a faulty signal will cause the control module to invoke the limp-home mode, which adopts a
mean signal value (programmed into the control module memory), to enable the vehicle to be driven until the fault can be
diagnosed and rectified.
In many early models faults are signalled by numerical trouble codes comprising two, three or four digits, which can be
interpreted by reference to the code tables in this manual. Later models have EOBD codes which are mandatory on new
vehicles produced after January 2000.
Trouble codes on early models may be displayed by an LED on the control module, or on the fascia mounted malfunction
indicator lamp (MIL). If this is not possible then an LED tester can sometimes be used at the data link connector (DLC).
If access to trouble codes is possible in this manner it is described along with the relevant code table.
Many later models and those that comply with EOBD regulations may require a scan tool to enable the trouble code
information to be displayed.
Self-diagnosis for fuel injection, mapped ignition and integrated engine management systems has been used for many years,
but with the more recently introduced electronically controlled transmissions and immobilizer systems, the scope for trouble
code based fault diagnosis has expanded considerably and the adoption of European On-Board Diagnostics (EOBD) has
brought a degree of standardisation.
Engine management
The engine control module (ECM) processes the load and temperature signals received from the system sensors and
controls the fuellair ratio, idle speed, ignition timing and other functions through outputs to the actuators, such as injectors,
idle speed control (1%) valve, evaporative emission (EVAP) canister purge valve etc.
As emission regulations have become more stringent, more systems, such as throttle control, cruise control,
transmissions and immobilizers have been linked to the ECM.
The ECM self-diagnosis fault memory will log trouble codes if certain inputs or outputs are outside the programmed
parameters and may invoke 'limp home' substitute values for any out-of range signals, to enable the vehicle to continue to
be driven until repairs can be carried out.

Electronically controlled transmissions
Most electronically controlled transmission systems have sensors monitoring load, selector lever position, gear change
strategy program, transmission output shaft speed, engine crankshaft speed, and speed of brake and throttle operation.
Signals from these are sent to a combined engine and transmission (powertrain) control module or a separate
transmission control module (TCM).
These inputs are processed by the transmission control module (TCM) and appropriate control outputs are sent to the
transmission.
Where a separate engine control module (ECM) and transmission control module (TCM) are used, these are linked and
data is shared between the two.
The self-diagnosis fault memory will log trouble codes when certain control module inputs or outputs are outside the
programmed parameters and may invoke 'limp home' substitute values for any out-of range signals.
There are several types of transmission that can have electronic control with self-diagnosis trouble code output:
Automatic
Semi-automatic
4 wheel drive
Automatic transmission: usually comprise a torque converter driven by the engine crankshaft and an epicyclic gearbox
with four or five forward ratios.
The mechanical operation of the transmission is actuated hydraulically, but with electronic controls, enabling several
different change patterns to be selected by the driver (e.g. sport, economy etc.). Smoother gear changes (using torque
reduction by retarding the ignition timing) and better matching of gear ratios to available torque, are also advantages.
Lower powered (and often front-wheel drive) cars may be fitted with a continuously variable transmission. This may be
driven via a torque converter, multi-plate clutch or magnetic coupling.
In this form of transmission a steel band is driven by a variable diameter drum and the output is from a similarly variable
diameter drum. It has no fixed ratios and finds its own 'ideal' ratio from the inputs of speed and load sensors.
Semi-automatic transmission: these are a comparatively recent innovation and use a conventional gearbox (helical spur
gears) with hydraulically operated clutch. Electronics are used to ensure smooth gear changes, prevent excessive engine
speeds and to 'blip' the throttle during down changes.
4 wheel drive: vehicles with a Haldex coupling between the front and rear wheels have electronic control of the centre
differential. Sensor inputs from the wheel speed sensors, stop lamp switch and other control modules (via a CAN data
bus) are used to govern the power distribution between the front and rear wheels.
The transmission systems covered by this manual have associated trouble codes which will be logged under certain fault
conditions.
These codes may be part of the engine management trouble code output (in the case of powertrain control modules) or
they may be accessed separately - refer to model-specific chapters.

Immobilizers
The immobilizer may be self-contained or integrated with the alarm system and remote control central locking, all
activated from the key. The central locking will be operated separately by either an infrared or radio frequency signal and
requires a self-contained battery supply.
The immobilizer may also be controlled by the infraredlradio frequency signal or separately by a transponder.
The transponder [I] is embedded in the ignition key [2] , and is activated by a read coil [3] in the ignition switch [4]. The
read coil is connected to the immobilizer control module [5] which is linked to the engine control module (ECM) [6].
The transponder uses induced power from the read solenoid and therefore does not require a battery supply.
When the ignition is switched on, the read solenoid induces a response from the transponder, which then transmits its
unique security code to the immobilizer control module.
The key code is compared with the stored code in the immobilizer control module and then matched with the 'rolling' code
in the ECM.
If all the criteria match, the engine will run normally.
If the immobilizer control module does not recognise the key code the engine will either not start or only run for a few
seconds.
The immobilizer is automatically reset when the key is withdrawn from the ignition switch.
Many immobilizer systems feature fault memories which can be accessed in various ways e.g. by counting the immobilizer
warning lamp flashes, bridging data link connector (DLC) terminals with a voltmeter or LED tester, or using suitable
diagnostic equipment - refer to model-specific chapters.

Trouble code format
Prior to 2000 there was no uniformity in the display, format
or method of retrieval of diagnostic trouble codes, each
vehicle manufacturer developing a dedicated system with
special diagnostic equipment and varying amounts of data
logging. Some systems having just a few one or two digit
codes while others had more comprehensive three and
four digit coding systems.
In many cases the codes for these early systems could be
displayed by connecting an LED tester between the
appropriate terminals of the data link connector (DLC) and
counting the flashes or groups of flashes.
For example Fig. shows a diagrammatic representation
of three LED (or MIL) flashes. The vertical scale
represents voltage and the horizontal scale represents
time, therefore the shaded areas represent the 'on' time
and the gaps in between represent the 'off' time.
The three short flashes, with a short pause separating
each flash, display trouble code 3. If more than one code
has been logged, a long pause would be used to separate
each code.
Fig. 4
Trouble codes
&I
Trouble codes
If the trouble code is greater than 9, long flashes are used
for the tens and short flashes for the units. For example
Fig. 5
Fig. 5 shows one long flash, and two short flashes
separated by a short pause, indicating trouble code 12.
In 1988 the California Air Resources Board (CARB)
introduced legislation covering all new cars sold in
1
2
California. These new laws governed on-board diagnostic
requirements for emissions related faults and began the
process of standardization in the US and eventually
Europe.
These regulations were known as onboard diagnostic
systems - phase I (OBD-I) and were subsequently
adopted by the vehicle manufacturers, for states other
than California.
The basic requirements of OBD-l were as follows:
A043243
A malfunction indicator lamp (MIL), to provide a visible
warning that an emissions related fault had been logged
by the engine control module (ECM).
Provision for the logging and storage, for subsequent
retrieval, of diagnostic trouble codes (DTC)/flash codes for
emissions related faults.
The location of the diagnostic socket, the method of
access to the trouble codes and the configuration and scope of the self-diagnosis was left to individual vehicle
manufacturers.
This resulted in an almost complete lack of standardization, requiring the technician to adopt different procedures and to
use different equipment for each vehicle.
In 1995 the California Air Resources Board (CARB), after consultation with the Society of Automotive Engineers (SAE),
introduced further legislation covering all new cars sold in California.
These regulations are known as OBD-ll and have been adopted for all states. They closely define trouble code logging
and retrieval. More significantly they require monitoring of the operation of the system and components, in addition to
detecting component failures.
OBD-ll also covers systems other than engine management.
Basically the US OBD-II regulations have been adopted for European vehicles and are known as EOBD - European On
Board Diagnostics.
These EOBD regulations became mandatory for most new petrol engined vehicles produced after January 1st 2000
(diesel and LPG engined cars were not required to comply until 2003). Most petrol engined vehicles already in production
before January 1st 2000 were granted exemption until January 1st 2001.

In cases where flash codes and EOBD codes are
listed for the same model range, only one flash code
will be generated for a particular component, but
there may be a list of many EOBD codes related to
this component. Alternatively there may be some
EOBD codes with no equivalent flash code(s).
These EOBD codes will provide more specific details
about the fault location, wiring, voltage signals and
other information relative to the circuit or system.
Logging faults with EOBD
Fault logging is based on inputs received during each
'trip' which may comprise a number of 'drive cycles'.
Each 'drive cycle' is initiated when the engine is
started and is terminated when the engine is
switched off.
For a complete 'trip' to be completed the following,
complex, conditions need to be met (and may take
several 'drive cycles' to complete):
Before starting the engine, coolant temperature
should be below 50°C and +/-6°C of ambient
temperature.
This ensures that the ECM logs a cold start.
n Allow engine to idle for 2-3 minutes with an
electrical load switched on (such as headlamps or
heated rear window).
This will ensure that the misfire monitoring and fuel trim
monitoring programmes run.
Drive vehicle up to at least 50 mph and maintain
this speed for at least 3 minutes.
Misfire and fuel trim monitoring will run.
Allow the speed to reduce to around 20 mph
without changing gear, using the brakes or the
clutch.
Fuel trim monitoring will run.
Accelerate to at least 50 mph and maintain for at
least 5 minutes.
Misfire and fuel trim monitoring will run.
n Allow the speed to reduce to around 20 mph
without changing gear, using the brakes or the
clutch.
Fuel trim monitoring will run.
Each 'trip' starts when the engine is started and
continues through a number of 'drive cycles' until all
the EOBD monitors have completed a self-test.
The EOBD monitoring programme provides
operating tolerance checks on all emissions related
sensors and actuators. Some components/circuits
are continuously monitored and some are only
activated under predetermined operating conditions.
Misfire monitoring detects irregularities in the
crankshaft position (CKP) sensor signal pattern and
identifies which cylinder misfired and if the misfire is
frequent enough to cause catalytic converter damage
due to excess internal temperatures. If this is the
case the MIL will flash.
If the misfire is likely to increase emissions above the
EOBD limits and occurs on each of two consecutive
'trips' the MIL will flash. If the misfire is absent during
the next three 'trips' the MIL will be extinguished.
When a fault code is logged a number of data
parameters are stored with it, to assist in accurate
fault diagnosis. These are:
n Vehicle speed
Engine coolant temperature
Engine rpm
cj Engine load
Oxygen sensor system status - open/closed loop
Distance since fault first logged
Long term fuel trim (LTFT) level
Most EOBD scan tools are capable of capturing this
'snapshot' of data and displaying (or printing) it for
analysis to aid the fault diagnosis process.
After rectification
EOBD monitoring is very sensitive and replacement
components may still be identified as faulty if their
specifications do not exactly match the originals.
The trouble code memory must be completely erased
and a 'trip' completed.
The trouble code memory should be accessed to
establish that no further codes have been logged.
All EOBD codes starting with P zero have standard meanings irrespective of vehicle make or model.
For EOBD codes, other than those starting P zero, refer to model-specific chapters.

General information
Refer to the front of this manual for general test conditions,
terminology, detailed descriptions of wiring faults and a
general trouble shooter for electrical and mechanical faults.
Trouble codes are displayed by using an LED connected to
the data link connector (DLC).
n The ECM fault memory can also be checked and erased
using diagnostic equipment connected to the data link
connector (DLC).
Self-diagnosis using flash type trouble codes may not
display all available diagnostic information.
Carry out road test for 10 minutes.
Accessing

diagnostic equipment connected to the data link connector
(DLC).
Accessing
Ensure ignition switched OFF.
Bridge data link connector (DLC) terminals 4 and 15 0.
Switch ignition ON.
Trouble codes will be displayed after a short flash H [A] and
a long pause H [B].
Count MIL flashes. Note trouble codes. Compare with
trouble code table.
Each trouble code consists of two groups of one or more
flashes.
The first group of flashes indicate the 'tens' of the trouble
code H [c].
The second group of flashes indicate the 'units' of the
trouble code H [Dl.
A short pause separates each trouble code group H [El.
A long pause separates each trouble code H [F].
For example: Trouble code 12 displayed H.
Each trouble code including 12 displayed three times.
Erasing
The engine control module (ECM) fault memory can only be
erased using diagnostic equipment connected to the data
link connector (DLC).
Repeat checking procedure to ensure no data remains in
ECM fault memory.
